Then, we have the appendage resistance. You have to calculate the appendage resistance and convert it to a coefficient so that you can add it to CT. And similarly, you have to have the wind resistance coefficient. Again, calculate the total wind resistance divide by the total weighted surface, how the CT is calculated, half rho s v square, that S may be changed to S plus appendage weighted surface. Then, you can calculate resistance for the total ship including that of appendage weighted surface. Then, you get CTs is equal to CTs(1) plus CA plus CApp plus CAA, all these will give you the actual ship resistance either at zero before or at before three- the CAA will determine that depending on what sort of trial condition you want to do.
